This report discloses a distinctive palladium-catalyzed sequential tandem cyclization reaction of two molecular haloalkynes and one molecular N-alkylanilines, leading to the efficient assembly of various 3-halo-1,2,5-triarylpyrrole derivatives. Two carbon-carbon triple bonds and one carbon-halogen bond in two molecular haloalkynes are transformed conveniently in one single step, which may involve the
